The performance scores use generally a scale ranging from 0 to 100 or 1 to 5 stars. The value of score is based on the comparison made between the rated house and a reference house that meets a desired energy code or standards.A rating of 50 indicates average energy performance, while a rating of 75 or more indicates best performance.
Energy performance certificates (EPCs) are a rating scheme to summarise the energy efficiency of buildings. [4] [5] The building is given a rating between A (Very efficient) - G (Inefficient). The EPC will also include tips about the most cost-effective ways to improve the home energy rating. Energy performance certificates are used in many ...

On average, low-cost weatherization reduces heating bills by 31% and overall energy bills by $358 per year at 2012 prices. Increased energy efficiency and weatherization spending has a high return on investment. [26] On August 4, 1977, President Jimmy Carter signed into law The Department of Energy Organization Act of 1977 (Pub. L. 95–91, 91 ...
Low Income Home Energy Assistance Programs (LIHEAP) and Weatherization Assistance Programs (WAP) work together to help low-income individuals and families pay energy bills and reduce energy costs. This article gives of overview of each program and describes how they work together. LIHEAP and WAP literature is also examined.
